Find the Gtid_list_log_event at the start of a binlog.

If ok, then the event is returned in *out_gtid_list. This can be NULL if we
get back to binlogs written by old server version without GTID support. If
so, it means we have reached the point to start from, as no GTID events can
exist in earlier binlogs.
